## Fee Market

To increase network stability, a fee market has been introduced. This adds dynamic fee rates to transactions on the network. For end-users, this means that each transaction will need to include a non-zero fee. You can read more in Skip's docs for [Changes for End-Users](https://github.com/skip-mev/feemarket/blob/f1f216e15aa6bcc05075a7079496764820a0f545/docs/UPGRADING.md#changes-for-end-users) and their [Integration Guide](https://github.com/skip-mev/feemarket/blob/f1f216e15aa6bcc05075a7079496764820a0f545/docs/INTEGRATIONS.md).
